STOP-COCK BOX FOR WATEROR GAS PIPES.

SPECIFICATION forming part of Letters Patent No. 358,696, dated March 1,1887.

Application filed A piil l7, 1884.

.To all whom, it may concern;

Be it known that we, LoUIs P. Bnrorrnnr and ANDREW FULLER, both of thecity of Bu ffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Stop-(Jock Boxes for XVater andGas Pipes, of which the following is a specification.

This invention relates to an improvement in the extensible or telescopictubular boxes which are placed in the ground over the streetcocks ofwater and gas pipes for the purpose of giving access to the cooks whenrequired.

The object of our improvement is to produce a simple, light, and durablebox of this charaoter; and ourinvention consists, to that end, of thei-mprovements,which will be hereinafter fully set forth, and pointed outin the claim.

In the accompanying drawings, Figures 1 and 2 are vertical sectionalelevations of our improved stop-cock box. Figs. 3 and 4 are horizontalsections in lines 00 0c and yy, Fig. 1, respectively.

Like letters of reference refer to like parts in the several figures.

A represents the upper and B the lower tubular part of the box. Theupper part, A, is fitted loosely over the lower part, B, so that theformer can be freely raised and lowered or turned on the latterinadjusting the length of the box.

or represents horizontal depressions, and 1) represents verticaldepressions or grooves formed in the upper tubular part, A, on the innerside thereof.

0 represents studs or projections formed on diametrically-opposite sidesof thelower part, B, near its upper end. The vertical grooves b arearranged on diametrically-opposite sides of the upper part, A, so as toreceive the studs 0 of the lower part, B. The ends of the horizontalgrooves a open into the vertical grooves b, so that upon turning onetubular part with reference to the other the studs 0 can pass out of thevertical grooves E into the horizontal grooves a. The latter are made ofsuch size as to confine the studs against vertical movement. Uponadjusting the parts A and B so that the studs 0 project into the groovesb the part A can be raised and lowered on the part are locked inposition by turning the part A on the part B so that the studs 0 enterthe horizontal grooves a. The grooves a and b do not increase thethickness of the metal, but form corrugations in the part A,which ismade of substantially the same thickness throughout, thereby forming alight and strong box.

D represents a hollow ear or extension formed on one side of the upperpart, A.

E represents the cover, which rests on the top of the upper part, A, andis provided with a lug or tongue, 6, which projects into the hol- 10wear D when the cover is in place.

f is a vertical screw passingthrough the ear D, and held againstvertical movement by heads f f, bearing, respectively, against the upperand lower sides of the ear D, the portions of the screw f which areseated in the top and bottom plate of the ear D being formed withoutscrew-threads.

G is a follower arranged in the ear D, uu derneath the tongue 6, andprovided with a screw-threaded opening in which the screw f works. Therear side of the follower G is made straight and bears against thestraight rear side of the ear D, whereby the follower is prevented fromturning and compelled to rise or descend upon turning the screw f. Thecover E is locked in position by turning the screw f so as to press thefollower against the under side of the ear 0, and is released by areverse movement of the follower.

H represents the elongated flaring base or foot formed at the lower endof the lower part, B, and provided in its flattened sides with notchesor openings h, to enable the base to straddle the servicepipe.

2' represent horizontal plates or flanges cast on the inner side of thebase H at both ends thereof, and on opposite sides of the notches h, to.give the box a firm support in the ground and prevent the surroundingsoil as much as possible from working into the lower part of the box,whereby the stopcock would be ob- 5 structed.

Our improved construction of the box re duces the weight, andconsequently the cost, of the box materially without sacrificingstrength, and permits the parts to be easily molded and 100 cast. italso protects the box to a large ex tent against moisture and.consequent rusting by reason of the upper and outer portion of I coverE, provided with atongue, e, a screw, f, r the box conducting themoisture down toward seated in the ear D, and a follower, G, applied IOthe foot of the box, and preventing the moisture to said screw,substantially as set forth.
